As appears from the 'average heights the men are below the 

 average computed from very large miinbers, the women above the 

 large-number average. Beyond doubt Theile thus overrated the body 

 weight of the former, but on the other hand underrated that of the 

 women ; in his time there were not yet so many data about the 

 correspondence of body weight and height available in the literature 

 as there are at present. 



In Table IV the average relative muscle weight of the women 

 has been calculated somewhat too low, as in two cases the total 

 muscle weight was put as double that of the lefthand side, without 



TABLE IV. — Body weight and weight of the muscles of 4 men and 4 women 

 (According to determinations by F.W. Theile. The body weights, 

 except of NO. 3, estimated by me) 



being balanced by other cases, in which the righthand side was 

 doubled. When on account of this the relative muscle weight is 

 put at 30"/,,, this will, indeed, be very near the real average of the 

 examined women, if their body weights have been correctly estima- 

 ted. The average relative muscle weight of the men must, on the 

 other hand, be considered as slightly too high, one of the men being 

 extraordinarily muscular. On account of this the average relative weight 

 of the muscles of the men, for so far as it is possible to approximate 

 it in sucti an estimation of the body weights, may be put at 38 " ,,
